Excellent!
Thank youd David and Jack for your time!

The pool will not actually go read only. All read and write requests
will block until both osds are back up. If I were you, I would use
min_size=2 and change it to 1 temporarily if needed to do maintenance
or troubleshooting where down time is not an option.

All right! Thank you very much Jack!
The way I understand this is that its not necessarily a bad
thing. I
mean as long as it doesnt harm any data or
cannot cause any other issue.
Unfortunately my scenario consists of only two OSDs therefore
there is
a replication factor of 2 and min_size=1.
What I am trying to figure out is if its more dangerous to have
min_size=2 rather than 1 in the above scenario and if it gives me
any
benefits.
I am already aware of the *golden* rule about the minimum number
of
replicas (3) but the cluster will be reformed soon and until then
I
would like to know if its better to go with min_size=2 or not.
